A while back i saw a post about how to de-stealth ppl by moving the object from under them does anyone know how to do this

The two ways I know of are to either TK or forceblast the object from underneath the stealthed figure.

A super strength character with Hypersonic Speed, Leap/Climb or Phasing may move past a stealthed figue and pick up the object under them, revealing them to your team mates.

abomination, vision, xplosion spiderman, doc samson, OWAW superman to name a few
